 ## Building blocks
 
 * DataFrame - Lazy data processing frame.
 * Rows - Immutable collection of `Row` objects.
 * Row - Immutable, strongly typed collection of `Entry` objects.
-* Entry - Immutable, strongly typed object representing cell in a row.
+* Entry - Immutable, strongly typed object representing a cell in a row.
 * **E**xtractor (Reader) - Memory safe, Data Source returning \Generator, yielding `Rows` to the `Pipeline`
 * **T**ransformer - Data transformer receiving and returning `Rows` (in most cases transformer), one instance of `Rows` at once.
-* **L**oader (Writer) - Memory safe representation of Data Sink, responsibility of Loader is to write `Rows` into destination storage, one at time.
